UNTTED STATES STEPHEN LON ERGAN,

S A W SPECIFICATION forming part of Letters Application filed July 26,1830.

To all whom it may concern:

Be it known that I, STEPHEN LONERGAN, of Lewiston, Maine, have inventeda new and novel Saw-Grage, of which the following is a specification.

The object of my invention is to provide a device to be attached to ahand or back saw, whereby the cut is exactly regulated to any requireddepth.

1 attain this object by the mechanism illustrated in the accompanyingdrawings, in which i Figure 1 is a view, in perspective, of the gageattached to a hand-saw as it appears after the removal of the studswhich are used for attaching a second saw. Fig. 2 is a View of thereverse side of one of the slotted arms of the gage, showing the head ofone of the studs before mentioned resting in the offset made in theedges of the slot to receive it. Fig. 3 is a front view of the gageattached to a hand-saw, with the second saw in position, and showing thefront stud. Fig. 4 is a side View of the second saw, showing the slotsin the same, through which the studs pass.

Similar letters refer to similar parts throughout the several views.

The bar G, Fig. l, furnished with the slotted arms h h, is clamped tothe blade of the saw A in a manner which will readily be seen byreference to Fig. 3, in which the block a is furnished with ascrew-threaded projection, (I, which passes through the slot in the armh, and also through a perforation in the clip a. The thumbnnt c is thenscrewed down upon the projection d until the blade of the saw A isfirmly clamped between the slotted arm h and the clip a.

it will be observed that the block a has an offset. When the gage is tobe used on a backsaw the back of the saw is placed between this offsetand the slotted arm h, and clamped there by means of the thumb-nut e.The arms 7117!. are slotted to enable the gage to be adjustable to anyrequired position, so that the saw will make a deep or shallow out.

When it is desired to use a second saw-as, for instance, in cuttinggainsthe studs 0 (only one of which is shown in the drawings) areadjusted to any required position in the arms Ii, and clamped there bymeans of the nuts '5, the studs being screw-threaded throughout theirlength. The nuts 1" are then adjusted so that the second saw shall bethe requisite distance from the blade of the saw A. The second saw, 8,is then clamped firmly in place by tightening the thumb-nuts ii). Theperforations in the saw-blade 8, through which the'studs 0 pass, areelongated vertically, so that it may be partly adjusted in thatdirection.

What I claim, and desire to secure by Letters Patent, is-

The saw-gage herein described, composed of the bar Gr, having slottedarms h h, said arms having suitable clips for clamping the gage to thesaw-blade, and having removable studs 0, provided with nuts 6 and r, andthumb-nut b, all for the purpose shown and described.
